高中物理教学中,测量物体内在和外在性质的仪器、仪表,对其进行正确的读数和记录,已经成为了当代素质教育的一种重要的素质训练.高中教学中所涉及到的物理仪器是相对简单的一类仪器.一般来说,仪器显示表中,最小分度是显示它每次测量的绝对误差的大小,误差出现的位数,就是仪器对物体测量的最小读取位数.所以,在进行实际测量时,一般可根据测量仪器的最小分度来确定读数.一、高中常见的几类仪器高中物理学中所涉及到的仪器大致可以分为三类:一类是不需要读出数值的仪器:滑动变阻器、打点计时器、示波器.另一类是需要明确读出数值:秒表、游标卡尺、电阻箱.最后一类是,应该估计读数的仪器,它包括刻度尺、弹簧测力计、螺旋测微器、电流表、天平、电压表、多用电表、温度表等.二、几种物理仪器估计读数的方法高中所涉及的几类物理仪器一般都有较为细密的刻度,但对物体的测量无法保证在准确的刻度上,所以
In high school physics teaching, measuring the inner and outer properties of instruments and instruments, and correctly reading and recording them have become an important quality training in contemporary quality education.The physical instruments involved in high school teaching are: Relatively simple type of instrument.In general, the instrument shows the table, the smallest graduation is to show that it is the absolute error of each measurement size, the number of bits of error, is the instrument to measure the minimum number of bits to read. , In the actual measurement, generally based on the smallest graduation of measuring instruments to determine the reading.A few common high school physics instruments involved in high school physics can be divided into three categories: one is not required to read The other is the need to explicitly read the values: stopwatch, vernier caliper, resistance box. The last category is that the instrument should be estimated readings, which include the scale, spring force Meter, spiral micrometer, ammeter, balance, voltmeter, multimeter, thermometer, etc. Second, several methods of reading the physical instruments High school involved in several types of physical instruments As has a more detailed scale, but the measurement of the object can not be guaranteed accurate in scale, so
